IMPROVEMENT IN VALVES FOR ARTESIAN WELLS, 84c.

Specification forming part of Letters Patent No. 141,708, dated August12, 1873 application filed July 12, 1873.

To all whom it may concern:

Be it known that I, J osnrn' FLEMING, of Shamburg, in the county ofVenango, State of Pennsylvania, have invented a new and Improved Valvefor Artesian Wells, of which the following is a specification, referencebeing had to the accompanying drawing, in which- Figure l is a verticalsection of the whole, Fig. 2 a perspective of the valve itself, and(Pig. 3 a horizontal section of tubes in cyliner. J

My invention relates to that class of valves which are used in pumps atthe bottom of Artesian wells, the valve in consideration being the loweror standing valve. The object of this invention is to construct a valvewhich will perform an equal amount of work with those now in use, and atthe same time free itself from. any dirt or other obstructions that mayclog its workings.

For this purpose, to the ordinary working barrel of a pump is attached ahollow cylinder, A, having, at a short distance from its base, tubesTT,joining each other in the center of the cylinder and terminating in itsouter circumference. At the point of intersection of these tubes ahollow screw, S, openinginto the tubes T T is provided for the receptionof the bottom or standing valve V of the pump. Below the tubes T T apipe is connected to the cylinder A by the screw 0, which serves as areceptacle for the dirt and other waste matter falling from the valves.The cylinder A is connected to the working barrel of the to the surfaceof the ground through the valve" V, as in any ordinary pump of the kind.Then. any dirt or sediment accumulating around the valves falls throughthe openings at a a into the receptacle B.

When necessary the whole apparatus is drawn from the well, thereceptacle R detached and cleaned out.

I do not claim as my invention the valve V.

I claim- 1. The combination of the cylinder A having the screw P, tubesT T, hollow screw S for the reception of the valve-case and valve V, andthe receptacle R attached by the screw 0, all constructed and arrangedsubstantially as shown and described.

2. The cylinder A, provided with the tubes T T and screw P, incombination with the hollow screw S, forming the valve-case for valve V,constructed and arranged substantially as shown and described.
